Known for its robust design, exceptional adjustability, and smooth ride quality, the DHX2 is often compared to its competitors in the rear shock market. This article will focus on the DHX2 Factory rear shock, its installation, maintenance, and troubleshooting, while also comparing it to similar models in the market.

Features of the Fox DHX2 Factory Rear Shock

The DHX2 Factory rear shock is a high-performance coil shock designed for aggressive riding styles. Key features include:

• Customizable Compression and Rebound Settings: The DHX2 offers separate high-speed and low-speed compression adjustments, providing riders with precise tuning options for varying terrain.
• Two-Position Climb Switch: The Climb Switch allows riders to adjust the shock for climbing efficiency and smooth descent handling.
• Enduro Proven: Built with heavy-duty seals and a durable design, this shock is designed to withstand the rigors of aggressive mountain biking.
• Factory Series Coatings: Featuring Kashima-coated stanchions, the DHX2 provides a buttery smooth feel and increased durability.

Installation of the Fox DHX2 Factory Rear Shock

Proper installation of the DHX2 Factory rear shock is essential for optimal performance. Here’s a step-by-step guide to ensure you install it correctly:

1. Prepare Your Bike: Ensure your bike frame is compatible with the DHX2 shock. Check the mounting points on your frame and make sure the eyelet diameter matches the shock.
2. Remove the Old Shock: If you’re replacing an existing shock, use appropriate tools to remove the old shock. Keep track of any hardware components for reuse or replacement.
3. Install the DHX2 Shock:
   • Slide the DHX2 shock into the mount on the rear triangle.
   • Use the provided mounting hardware to secure the shock. Tighten the bolts according to the manufacturer’s torque specifications to avoid damaging the frame or shock.
4. Set the Sag: Before adjusting other settings, set the sag of the shock to the recommended percentage (usually 30%). This will ensure proper suspension travel and performance.
5. Fine-Tune Adjustments: Once the shock is installed, make fine adjustments to the air pressure (if applicable) or preload to suit your riding style.

Adjusting and Maintaining the DHX2 Factory Rear Shock

After installation, it’s essential to regularly adjust and maintain the DHX2 to maintain peak performance.

Adjusting the DHX2 Shock

• Compression Settings: Use the high-speed and low-speed compression dials to adjust for different trail conditions. The high-speed setting controls the shock’s response to fast hits, while the low-speed setting adjusts for slower impacts like trail chatter.
• Rebound Adjustment: The rebound knob allows you to control how quickly the shock returns after compression. Adjust this based on your riding style and the type of terrain.
• Climb Switch: Engage the Climb Switch when riding on steep climbs to stiffen the shock, improving pedaling efficiency.

Maintaining the DHX2 Shock

• Regular Cleaning: Keep the shock clean by wiping down the body after every ride. Ensure that dirt and debris don’t interfere with the shock’s performance.
• Check for Leaks: Periodically inspect the shock for any oil leaks around the seals or adjusters. Leaking oil could be a sign of worn-out seals that need replacement.
• Lubrication: Ensure that the shock’s moving parts, such as the damper, are properly lubricated. Fox recommends using their specific lubricant for optimal performance.

Troubleshooting Common DHX2 Issues

If you encounter issues with your DHX2 shock, here are some common problems and their solutions:

• Shock Bottoming Out: If the shock bottoms out on rough terrain, it may be too soft. Increase the preload or air pressure, depending on your shock type.
• Poor Rebound: If the rebound is too fast or too slow, adjust the rebound knob to achieve the desired speed. If the issue persists, it could indicate a need for servicing.
• Sag Issues: If you can’t achieve the correct sag, ensure that your shock’s spring rate matches your weight. You may need a heavier or lighter spring for optimal performance.

Customizing the DHX2 for Better Performance

One of the most appealing features of the Fox DHX2 Factory rear shock is its adjustability. To achieve the best performance, consider the following customizations:

• Spring Rate Selection: Choose the right spring rate based on your weight and riding style. If you’re unsure, refer to Fox’s spring rate chart or consult with a suspension technician.
• Compression and Rebound Fine-Tuning: Spend time fine-tuning the compression and rebound settings to match your trail conditions. Small adjustments can significantly improve ride comfort and control.
• Service and Upgrades: Fox offers a range of aftermarket components and upgrade kits, such as higher-quality springs or upgraded seals, which can further enhance the shock’s performance.

Comparing the DHX2 Factory to Competitors

When choosing a rear shock, it’s important to compare the DHX2 to other high-performance models in the market. The DHX2 competes with shocks from brands like RockShox, Öhlins, and Cane Creek. Let’s compare it to some of these models.

Fox DHX2 vs. RockShox Super Deluxe Coil

• Performance: The DHX2 offers superior compression and rebound adjustment, making it more customizable than the RockShox Super Deluxe. However, the Super Deluxe has a slightly lighter weight, which may be preferable for riders focused on weight reduction.
• Durability: The DHX2’s Kashima-coated stanchions provide superior durability and smoothness, particularly in harsh conditions. The Super Deluxe also offers good performance but doesn’t match the longevity of the DHX2.
• Price: The DHX2 is typically priced higher due to its premium features, while the Super Deluxe offers good value for money in a slightly lower price range.

Fox DHX2 vs. Öhlins TTX22M

• Performance: The Öhlins TTX22M is renowned for its smoothness and performance on technical terrain. However, the DHX2 provides more comprehensive adjustability, especially for riders seeking fine-tuned customization.
• Weight: The Öhlins TTX22M is lighter, making it a good option for riders who prioritize weight savings over ultimate adjustability.
• Price: The TTX22M is comparable in price to the DHX2, though it is often favored by riders who need extreme smoothness and handling.

Fox DHX2 vs. Cane Creek Double Barrel Coil

• Performance: The Cane Creek Double Barrel Coil features a unique twin-tube design for more precise adjustments, but it requires more maintenance compared to the DHX2. The DHX2 is easier to set up and maintain.
• Durability: Both shocks are built for heavy-duty performance, but the DHX2’s Kashima coating offers slightly better protection against wear and tear.
• Price: The Cane Creek Double Barrel is often priced similarly to the DHX2, but it may require more frequent servicing due to its design.

Compatibility with Other Drivetrain Components

The Fox DHX2 Factory rear shock is compatible with a wide range of drivetrain systems, including SRAM and Shimano setups. However, it is essential to ensure that your bike’s frame and linkage are designed to accommodate a coil shock, as some lightweight frames are only compatible with air shocks. Always consult your bike manufacturer’s specifications to ensure compatibility.
